Score monitoring and display device for tennis players

Invention relates to a game status monitoring and
display device for tennis players according to the preamble of claim 1.

From DE-OS 30 38 094 a tennis game display device is known which is designed in the form of a wristwatch.

By pressing several buttons, the players get results entered into the device so that the score can be read from the device.

Such a device has the disadvantage
that the operation is very complicated, so that the players are distracted. In particular, such counting devices are not adapted enough to the gaming habits. So far they could
do not enforce such devices. In particular, it must be pointed out that in the case of a double game, that is, if four
Players each wear a watch-like display device, the risk of incorrect input is very high.

It is the object of the invention to provide an easy-to-use monitoring device which, in a sense, replaces a referee and display device for tennis games.

The device is intended to enable a player to use the current score is recorded and visually displayed for the opponent and the audience while the other

Player can monitor the accuracy of the ad.

In particular, the device should be designed in such a way that it does not interfere with the normal course of the game, i.e. that for the Operation of the facility the course of the game does not have to be changed in any way or is impaired.

A device for solving this problem is described in the parent application P 33 34 585.6. 10

It is the object of this invention to improve and further develop the subject matter of the parent application.

The object is achieved by the features laid down in the characterizing part of the claims.

By designing the stationary control unit with the plus and minus buttons as a portable, wireless control unit, For example, as an operating unit that works by means of ultrasound, for example in the form of a wristwatch, the player is given the opportunity to score his plus or minus points from anywhere on the field to display and thus to give the opponent and the audience the opportunity to co-control and to monitor, with an acoustic signal announcing any change in the game score.

Players do not need to go to the edge of the field to view their scores, which eliminates the application of the 7Λ Score and monitoring facility even easier so that the operation of the device can in no way interfere with the normal course of the game.

The advantages of such a device are made insbeson _r broader that the wearing including a keyboard. A

y \ minisenders don't bother you because the players are already used to it by wearing a wristwatch. By operating the armband keyboard, the opponent and the audience are constantly informed of the latest game status (not only at the end of the game, as is common practice). Thus, by means of the overall device according to the invention, it is achieved that following the competition becomes much more exciting.

>] O Only by pressing the plus or minus point key all counting work is done, with the further addition of the points, the games, the sets and a pending change of sides by a program that follows the rules of tennis (including the tie-break rules) and is based on the display device is made visible.

Since the portable control units with different transmission frequencies can only be used for the transmission frequency due to the small computer built into the display device the portable operating unit of the server, while the transmission frequency of the operating unit of the receiver is blocked.

The computer is programmed in such a way that it uses the reception channel of the portable control unit when there is a pending change of page the recoil locks so that no more signals can be received from this portable control unit, whereby it is indicated to the players that a change of sides must occur.

The game is controlled by the monitoring and display device

monitored and controlled in every phase and situation, which is a great relief, especially for recreational tennis players. Such advantages are particularly _c significantly because recreational tennis players often without arbitration

judges have to get along, but still one constantly wish current, indisputable score.

A preferred embodiment of the invention is shown in the drawing explained.

Show it:

Fig. 1 is a perspective view of a tennis court.

2 shows an example of a display device.

Fig. 3 other positions of the display device and 4 device.

5 shows an operating unit.

In Fig. 1, a tennis court is shown with the respective service fields 1, the net 2 and the field fence 3.

Two portable operating units 25, 26 in the form of a wristwatch are shown, which are equipped with a display device 7 either via infrared, ultrasound, laser or via modulated RF waves with a corresponding receiver 27 in Connected. A special frequency modulation can prevent third parties from accessing the display device can be acted upon.

The operating units 25 and 26 have a plus button 28 and

a minus key 29. The one trained with a receiver Display device 7 is programmed accordingly Connected computers that on the display device 7 on-Lr and by pressing the plus or minus key, the respective

show the current score. Appropriately is a small computer installed in the display device.

The display device 7 shown in Fig. 2 shows the names the players or pairs in fields 17 and 18. The control lamps 10 behind the names are indicated by the computer switched on when the player has the right to serve, while at the same time the receiving channel for the control unit of the recoil is blocked in order to avoid incorrect operation.

In the fields 11 and 12 are in the first three places the results of the respective sentences are displayed from left to right.

In the fourth position 11a or 12a of fields 11 and 12 is the current score is displayed.

If there is a tie of 40:40, the following is displayed Points in fields 11a and 12a by displaying Cross lines or illumination of a control lamp 16 (Fig. 3 and 4).

When specifying an advantage, i.e. when one point is ahead of a player or pair of players is shown instead of the points in both fields 11 and 12 in field part 11a and 12a a horizontal line is displayed. In order to be able to use the usual number display for this purpose too, this line indicated by the horizontal line of the number 4 shows, whereby the display device manufactured more cost-effectively can be.

Fixed labels are attached to fields 13, 14 and 15 for Advantage and Deuce.

If now the above-mentioned horizontal line in field part 11a (Fig. 3) at the server (indicated by the control lamp 10 lights up, it indicates that the server has one point more.

Figure 4 shows the Deuce display, i. Lamp 16 is switched by the computer when both players are tied.

if a score of 6: 6 is reached in a set, the computer switches to the tie-break rules and also displays such a score in fields 11a and 11a. 12a for display.

As already explained in more detail at the beginning, pressing the plus and minus keys 28, -29 a flawless and The current score is always displayed without the need for a referee, with mutual monitoring is made easier by the players or the audience by acoustic signals. By pressing the plus or Minus button, an acoustic signal is triggered on the display device and after a short time Delay of one second, for example the progressed score is made visible on the display device 7.

For example, if you hear a short double beep, know the receiver, whose receiving channel is blocked anyway is that the server has pressed the plus or minus key and can by looking at the display device 7 he effortlessly check whether the point was entered correctly, which is particularly evident due to the time lag between acoustic signal and switching of the display device upq is made much easier.
